According to the upload, this clip is the screech linked to Acephalous from Five Nights at Treasure Island: The Revenge, a fan-made horror game in the Five Nights at Freddy's universe. The embedded file tag names it Goodyshout2, which points to it being pulled from a community sound archive rather than an official soundtrack. Like many FNaF fan-game jumpscare sounds, it circulates through collections and soundboards where creators grab short, high-impact stings. Its harsh, instantly recognizable shock value keeps it in rotation for horror memes and edits.
